Figure 5. Epiphytic tropical ferns are not more drought tolerant than terrestrial or hemi-epiphytic tropical ferns. (a) Raw results from 211 pressure–volume curves from 38 tropical fern species. Box plots of turgor loss point (b) and osmotic potential at saturation (c) across tropical fern life forms. Relationship between tissue capacitance at full turgor and the bulk modulus of elasticity for tropical ferns (d) and box plots of the tissue capacitance after turgor loss (inset). Fits for panels (a) and (d) for each fern life form uses loess regression for visualization purposes. Box plot widths are proportional to the number of measured species in each life form.
GOOD:
Germination rates were significantly higher after 24 hours in running water compared to controls (Figure 4).
DNA sequence homologies for the Eyeless gene from three strains show high identity (Table 1).
BAD:
Table 1 shows the summary results for male and female heights at Shepherd University. See the table below for a summary of the relevant literature on tumors.
Minimal differences in leaf pressure–volume parameters were detected among the three life forms (Figure 5a). The turgor loss point (Ψtlp) marginally varied by life form (p = 0.051) and post hoc comparisons did not detect differences in Ψtlp across terrestrial, hemi-epiphytic, or epiphytic ferns. Broadly, terrestrial and hemi-epiphytic fern species had trended towards slightly lower Ψtlp than epiphytic species (Figure 5b). The osmotic potential at saturation (Ψo) was also lower in terrestrial compared to epiphytic species (p = 0.009, Figure 5c), while the modulus of elasticity (ε) was similar across all life forms. The relative water content at turgor loss point did not vary between fern life forms. The tissue capacitance between saturation and turgor loss (Cft) was not different between life forms, however; the tissue capacitance after turgor loss (CTLP) was 54% lower in epiphytic compared to terrestrial species (p = 0.009, Figure 5d insert). Additionally, Cft declined quickly with increasing ε for all species (Figure 5d)
